PiPO 7-inch

I am looking at PiPO after seeing some discussions here. However, I am looking for a 7-inch tablet instead of the more popular 9.7" and 10.1" models. PiPO website is kinda confusing as I do not see any U1 or S1 listed there. Are the models named differently on the website?

Anyone with experience with S1 or U1?

I am currently using a Wopad i7 so it definitely is nearing the time for a replacement soon. 512MB RAM and Android 2.3 are just not enough for me.

I had a U1 briefly which someone asked me to configure for them. It seemed a bit laggy which was probably due to the default launcher used by Pipo but the screen was nice. I did a much more detailed review of the Cube Mini and think it is the better device overall despite the lower resolution display (you cannot really see the difference when the screen is only 7 inches). I think these devices all have quite small batteries so don't expect long battery life on a full charge especially when playing games.
